    Where is the dark energy coming from?

    By this I associate the following questions -

    Is there a general location in the cosmos where it is originating from?
    Is there a specific axis(s) that can be determined by watching the direction of flow throughout the Universe?
    Is the expansion uniform in velocity?

    Upon which I speculate, if it started roughly a billion years ago and began significantly increasing roughly 200 million years ago
    What does this say about the shape of the Universe?
    Is dark energy an equilateral expansion or a shotgun blast?

    Regards, Novawatcher

    Very little is known about dark energy, except that it is needed to explain the acceleration of the universe's expansion. It is assumed to be uniformly distributed throughout the universe.

    What kind of energy it is?
    It is a form of vacuum energy; you can picture it as a property of the vacuum itself.

    I can't say, because the origins of DE are yet to be explained, so I have no answer to the above. There is a possibility that it is related to ann inflation-like quantum field.
